Abstract

Black tea leaves are oxidized to provide treated leaves from which aqueous tea extracts which have minimal turbidity, particularly when cooled, may be obtained. The oxidation reaction is performed on black tea leaves which contain moisture only in an amount such that the oxidation reaction occurs at localized sites on and within the tea leaf structure.
